Hi,

I noticed that everytime my RB5 bootup, the MAC address of the WiFI interface is different. So the dhcp server will give out different IP address. It is difficult to ssh into it if its IP changes everytime.

Is there a way for assign a permanent MAC address to the WiFi?

Thanks!

@Dong-Liu Unfortunately that is a bug with the SD865 SOM. We've had a ticket open with Qualcomm for a long time with no solution yet.

You basically just need to create a systemd service file to set the IP on boot.
